It definitely is very complicated. We didn't want to gear down a shaft on our winch to only rotate 10 turns over 6'. We ran the numbers and we were aiming for more precision than we would be getting with a pot. We also have a large electronics and software team this year so we have an entire subteam working on this one sensor. They have made lots of progress and it actually is working really nicely.
There are a number of benefits most notably precision (1/8" over the whole travel). After this year we may package up the sensor so it's easy to reuse.
